Wal­lets and Cash­back

I am amazed at the way Paytm ad­ver­tises about its cash­back of­fers, al­though it is nowhere close to what it used to of­fer ear­lier. Now I don’t get any cash­back on mak­ing pay­ments for my Air­tel bills. How­ever, com­pa­nies are ag­gres­sively link­ing it to shop­ping. I re­cently earned `300 on shop­ping of `3,000 on Jabong. I wish more com­pa­nies would tie up with wal­lets such as Paytm and Freecharge. RENUKA SINGH, on e-mail
